well I got my answer thx guys .I got this x5 in june and it has never been undercoated and the underneath of the vehicle is mint other than some linkages with rust on them and the rear brake calipers have rust .looks like the front calipars and pads are new no rust. and no rust on body never been painted before . couple small dings on 1 of the doors and 1 ding on front fender
realy small dings but it bugs me since I use to do bodywork a few years ago I notice everything .
